Total cost for cookie and lemonade is 1.80. If lemonade costs 1.00 more than the cookie, how much was the lemonade?

Ray Of Light [21]

Answer:

The lemonade costs 1.4.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

x is the cost of a cookie.

y is the cost of a lemonade.

Total cost for cookie and lemonade is 1.80.

This means that $x + y = 1.8$ .

As we want y, we have that $x = 1.8 - y$

Lemonade costs 1.00 more than the cookie?

This means that:

$y = x + 1$

$y = 1.8 - y + 1$

$2y = 2.8$

$y = \frac{2.8}{2}$

$y = 1.4$

The lemonade costs 1.4.

Find the slope of (0,1) and (2,7)

gavmur [86]

Slope is $\frac { y_{2} - y_{1}}{ x_{2} - x_{1}}$

if we plug in your coordinates we get:
$\frac { y_{2} - y_{1}}{ x_{2} - x_{1}} \\ \frac {7-1}{2-0} \\ \frac {6}{2} \\ 3$

Therefore, the slope of (0,1) and (2,7) is 3.
